Default led light strips and carbon fiber,easy short circuit!

i have to share this with everyone who is doing carbonfiber quad building and adding led light to assist in LOS flights.

i added the home made light bar underneath the quad using strips of balsa to make a frame and stuck the strip led lights on it so i had green in front and red in back. this was nice but i was still having issue at a distance telling front to back and orientation could be very difficult. the balsa was to keep the lights separate from the carbonfiber plates.

so i made a light bar using carbon fiber rod and stuck the sticky side of the led lights to it. then i hot glued a dji type headlight of leds to the center. it was perfect for both orientation and night flying. as you may be able to see in the pictures,the motor that over heated and the alum spacer rod that got hot were the same side where the light bar led copper was making contact with the carbon fiber arm of the quad.

i plan on isolating the led strip using a plastic stip instead of carbon fiber and also make sure the led copper side makes no contact to the frame and test it out again. i am glad there wasn't any smoking parts and am hoping the motor is still ok. will know later when the rain stops. the fact that this short didn't stop the quad from flying is a mystery.
